About M4A files
M4A (MPEG-4 Audio) is a high-quality audio format developed by Apple, based on the AAC (Advanced Audio Coding) standard. It offers better sound compression than MP3 while maintaining excellent audio quality, making it ideal for music and podcasts. M4A files are often used in iTunes and Apple devices, supporting lossy compression with smaller file sizes than MP3 at similar quality levels. Though less universal than MP3, it is widely supported on modern devices and media players.
About OGA files
OGA (Ogg Audio) is an open-source audio format based on the Vorbis codec, part of the Ogg multimedia container. It provides high-quality sound at small file sizes, making it ideal for streaming and web audio. OGA is widely supported in Linux systems and open-source software, though less common on proprietary platforms. Licensed under the BSD license, it allows unrestricted use, making it a favorite for developers and content creators who prioritize freedom and quality.
